One day it is too hot and other days it is too cold. Do we need to replace the HVAC system? part of SISL:2012 Sustainability in Math Workshop:Activities
Monika Kiss, Saint Leo University
This project will allow students to create a mathematical model to help in making decision about replacing HVAC units on a large scale.

What's for Dinner? Analyzing Historical Data about the American Diet part of SISL:2012 Sustainability in Math Workshop:Activities
Jessica Libertini, Johns Hopkins University
In this activity, students research the historical food consumption data from the U.S. Department of Agriculture to observe trends, develop regressions, predict future behavior, and discuss broader impacts.

A Monarchy Deposed: The Demise of the Monarch Butterfly part of SISL:2012 Sustainability in Math Workshop:Activities
Daniel Abel, Coastal Carolina University
Monarch butterflies (scientific name: Danaus plexippus) migrate annually to forests in central Mexico from Canada and California. Those surviving the 1200 - 2800 mile migration overwinter in Mexico. In this activity, students will learn about the conservation biology of monarch butterflies, threats to their survival, the implications of their potential extinction, and ways to protect the species.

Applying Quantitative Reasoning to Biodiversity part of SISL:Activities
Kenneth Mulder, Green Mountain College
A series of 6 Excel-based projects on the mathematics of biodiversity for basic college math classes and developmental math classes. Students learn about the structure of biodiversity, the application of many basic data analysis skills, and the use of Excel for analysis and data presentation.

Salt Marshes: estimation techniques using basic algebra and geometry part of SISL:2012 Sustainability in Math Workshop:Activities
Yelena Meadows, Upper Iowa University; Sharareh Nikbakht, Appalachian State University
The activity allows for learning about salt marshes ecosystem and practicing of basic math in estimations.

The Costs of Your Commute: Your Money, Your Time, and the Earth part of SISL:2012 Sustainability in Math Workshop:Activities
Charlie Buehrle, Harrisburg Area Community College-Harrisburg
This activity has students investigate their own cost, CO2 output, and time for commuting. They then compare their commute to an environmentally conscious alternative by using comparable metrics.

How Big is Your Breakfast Footprint? part of SISL:2012 Sustainability in Math Workshop:Activities
Ben Galluzzo, Shippensburg University of Pennsylvania
Calculation of a carbon footprint resulting from common breakfast choices illustrates the importance of contextualization.

Arctic Sea Ice Extent part of SISL:2012 Sustainability in Math Workshop:Activities
Bill Bauldry, Appalachian State University
Student teams investigate Arctic Sea Ice by analyzing actual data and making predictions. A worthwhile extension is to predict the first year that the Arctic Ocean will be ice free.

Solar panel statistical tests part of SISL:2012 Sustainability in Math Workshop:Activities
Owen Byer, Eastern Mennonite University
In this activity, students will determine whether there is a statistically significant difference in the number of watts of power produced on individual solar panels at Bryn Mawr College.

Sustainability Efforts on Our Campus: A Mathematical Analysis part of SISL:2012 Sustainability in Math Workshop:Activities
Lori Carmack, Salisbury University
In these open-ended but simple activities, students use basic mathematics and descriptive statistics to analyze campus sustainability efforts.
